From the article:
“UPDATE: There is an alleged manifesto posted to 8chan that contains white supremacist rhetoric, however it has not been confirmed as genuine.”
I can spot fake white supremacist rhetoric a mile away.
Read the manifesto. I don’t see a 21 year old loon writing that. First of all, it is a mish-mash of left and right and it seems to me a little bit too literate and well punctuated. I am not saying the syntax is perfect, but at this point I think it is not of his hand.
